Left:Invariant mass distribution of \lmb {\ensuremath{\pi}\xspace} pairs for $\Sigma(1385)^{+}$ after subtraction of the mixed-event background in 0--10$\%$ central \PbPb collisions and $3.5 < p_{\rm T} < 4.5$ \GeVc. \\Right:Invariant mass distribution of \lmb {\ensuremath{\pi}\xspace} pairs for $\Sigma(1385)^{-}$ after subtraction of the mixed-event background in 30--50$\%$ centrality class and $2.5 < p_{\rm T} < 3.5$ \GeVc. The black curves represent the combined fit using a signal (continuous blue line) plus residual background (red dashed line) model, as described in the text.
